The diaphragm is not truly an involuntary muscle, not in the same way that,
say, the heart is. The problem with the diaphragm is a lack of sensory
nerves, and the lack of knowledge of what it feels like. If you breath in,
and hold your breath without closing your throat (epiglottis - but please
someone correct me if I'm wrong), then you will start to feel the
antagonistic relationship as your diaphragm controls the outflow of breath.
I feel this as a buoyant "floating" feeling in my abdomen. Obviously if the
diaphragm were a truly involuntary muscle, then you wouldn't be able to hold
your breath in this manner.
